The Pokemon Masters Twitter account has updated with details about a newly introduced device in the game: The Poryphone.
Previously seen in the first official trailer, the Poryphone is a Porygon-themed smartphone that trainers in Pasio use to access various features and information. Presumably, this device is how players will manage their teams and Sync Pairs in-game. It is unknown whether this phone contains a Porygon in the same way the Rotom phone contains a Rotom.
